Donald Trump has been criticised for a bizarre tweet in the wake of the wedding of Princess Eugenie and Jack Brooksbank.

A day after the wedding, President Trump posted the following:

"Princess Eugenie of York was a truly beautiful bride yesterday," he wrote. "She has been through so much, and has come out a total winner!"

Royal Commentator Victoria Arbiter was quick to jump on the Tweet, calling the US President out for his choice of words.

"I'm sure she appreciates the sentiment, but it's weird with Trump," she writes. "Women always have to fall under the category of 'beautiful'.

"I'm going with her being brave, strong and inspiring for revealing her scars."

While many were quick to point out that Princess Eugenie was beautiful on the day of her nuptials, Victoria explained her discomfort at Trump's tweet, jumping back into the thread to say, "She was -- she was stunning, but for Trump beauty seems to be a woman's only attribute."

Many agreed with Victoria, with one Twitter follower taking issue with Trump's attitude to all women.

"I'm almost sorry to say this, but for Trump being beautiful includes having had a breast enlargement," they tweet. "It's true. He's mocked women before he was president about this. I have never called him 'my' or 'the' president. I always say the person sitting in the chair is the WH."

There were those who jumped to Trump's defence, suggesting his comments were sincere.

"Trump describes anything great as 'beautiful.' People things policies. My dad did that. Maybe it's an old guy thing. He meant well. You know when the @realDonaldTrump doesn't mean well. He does not mince words."

Then an even more bizarre suggestion alluding to a conspiracy against Meghan Markle, the Duchess of Sussex.

"I think this was a 'subtle' dig at Meghan. He never does or says anything that has no hidden or double meaning. By him tweeting about some insignificant Royal in this way, he's just reminding everyone he did not tweet about the major one similarly #harry #meghan."
